Could it be that there is something wrong with the Power Management of HDDs in OMV?
I am measuring the Power Consumption in IDLE with 42W, no matter what I do.
Here are my system specs.
1x Pentium G3220 CPU
1x SAMSUNG HD103SJ
2x 4TB WD RED
1x Sata Card
I feel like the HDDs are not spinning down...
APM - 127
Minimum Performace, Minimum Acoustic
